ARM: Make arch_specific_insn a define for new arch_probes_insn structure
Because the common underlying code for ARM kprobes and uprobes needs
to share a common architecrure-specific context structure, and because
the generic kprobes include file insists on defining this to a dummy
structure when kprobes is not configured, a new common structure is
required which can exist when uprobes is configured without kprobes.
In this case kprobes will define a dummy structure, but without the
define aliasing the two structure tags it will not affect uprobes and
the shared probes code.

ARM: Add an emulate flag to the kprobes/uprobes instruction decode functions
Add an emulate flag into the instruction interpreter, primarily for uprobes
support.

ARM: Change the remaining shared kprobes/uprobes symbols to something generic
Any more ARM kprobes/uprobes symbols which have "kprobe" in the name must be
changed to the more generic "probes" or other non-kprobes specific symbol.

ARM: Make the kprobes condition_check symbol names more generic
In preparation for sharing the ARM kprobes instruction interpreting
code with uprobes, make the symbols names less kprobes-specific.

ARM: Remove use of struct kprobe from generic probes code
Change the generic ARM probes code to pass in the opcode and architecture-specific
structure separately instead of using struct kprobe, so we do not pollute
code being used only for uprobes or other non-kprobes instruction
interpretation.

ARM: use a function table for determining instruction interpreter action
Make the instruction interpreter call back to semantic action functions
through a function pointer array provided by the invoker. The interpreter
decodes the instructions into groups and uses the group number to index
into the supplied array. kprobes and uprobes code will each supply their
own array of functions.

ARM: Move generic arm instruction parsing code to new files for sharing between features
Move the arm version of the kprobes instruction parsing code into more generic
files from where it can be used by uprobes and possibly other subsystems. The
symbol names will be made more generic in a subsequent part of this patchset.
